vue-lazyload图片延迟加载插件

1、首先在npm上下载vue-lazyload的引用包


npm install vue-lazyload --save-dev



2、然后我们在main.js里面import这个包，当然，单单这一个包是不够的，还得其他的文件


import Vue from 'vue';
 import App from './App.vue';
 import router from './router';
import VueLazyload from "vue-lazyload"



3、然后我们配置vue-lazyload


Vue.use(VueLazyload, {
error: 'static/error.png',//这个是请求失败后显示的图片
loading: 'static/loading.gif',//这个是加载的loading过渡效果
 try: 2 // 这个是加载图片数量
})



4、具体配置api可以看下图






html

<template>
 <div>
<ul id="container">
 <li v-for="img in list">
 <img v-lazy="img">
 </li>
</ul>
</div>
</template>





JS

<script>
export default {
    data () { return {
             list: [ 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb', 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb', 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb', 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb', 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb', 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb', 'http://st2.depositphotos.com/thumbs/2627021/image/9638/96385166/api_thumb_450.jpg!thumb',
            ]
        }
    }
 }
</script>
